migrate-database-schema allows you to manage database schemas that have been installed by DBIx::Migration::Directories. Using this script, you can view information on your installed schemas, install new schemas, and upgrade/downgrade/remove existing schemas.

Ignore what the database says, assume the current schema version is number. This is mostly useful with MySQL databases, since they are incapable of rolling back DDL changes if a migration fails. If this happens in MySQL and you need to "roll back", make sure you have a well-written backwards migration (eg; "DROP TABLE IF EXISTS" instead of "DROP TABLE") and use the arguments, "--force-current-version=[new.version] --desired-version=[old.version]"
